Toray TMG10D Ultra Low Pressure Brackish Water RO Membrane | 4" x 40" | 2,650 GPD | 99.7% Rejection

Toray TMG10D – Ultra Low Pressure Brackish Water RO Membrane Element (4040) Genuine Toray TMG(D) Series membrane designed for energy-efficient operation on low-to-moderate salinity feed water. The TMG10D delivers high permeate flow at significantly lower operating pressure than standard brackish membranes, reducing energy costs while maintaining excellent salt rejection.
